Here’s a script to show you the privileges given to one or more specified users. Done quick & dirty so please feel free to beautify it.
The script shows all SYSTEM-privileges (granted by role or direct) and OBJECT-privileges and also the tablespace-quotas granted to the given user-schema.

To hand over more than one user to the query, you have to use a little odd syntax:

USER1','USER2','USER3

Notice that you have to omit the leading and trailing single quotation marks.

If one has to manually download all the stuff from a given SVN-branch, this could be a very tedious task right-clicking every thing and saving it to local disk. Luckily this could be automated via wget, which comes with most Linux distributions (there are Windows-ports out there too).

“-e robots=off” ignores the robots.txt
“–wait 1” waits 1 second between the downloads
“-r” scans the server recursively
“-I /svnroot/mediawiki/trunk/extensions/SemanticForms/” includes the given path and below (excluding all the rest)

The latter one (“-I …”) is important! If omitted, wget would scan the whole server up and down – not limited to the “SemanticForms”-subdir.

Edit 2012-05-22:
There is an easier way of limiting the wget-operation to the given branch: the “-np” option. This switch keeps wget from ascending to the parent directory. So you could omit the -I mentioned above and use -np instead to get the same result with less typing. (Thank you Joe for the advice!)
